JOHN HEARNE, OF NEW' YORK, N. Y.

GAS-PU'RIFIER.

SPECIFICATION forming part of Letters Patent No. 433,126, dated July 29,1890.

Application filed March 3, 1B90| Serial No. 342,410. (No model.)

To all whom it may concern;

Be it known that I, JOHN HEARNE, of New York, in the county and State ofNew York, have invented a certain new and useful Improvenient inGas-Purifiers, ot which the following is a speoication.

My improvement relates to so-called puriiie1boxes,inwhich are placedchemicals, over or through which illuminating-gas is passed in order topurify it.

I will describe a purifier-box embodying my improvement in detail, andthen point out the novel features in claims.

In the accompanying drawings, Figure l is a vertical central sectionthrough two compartments of a box and the outlet-pipe common thereto.Fig. 2 is a top plan view of the same, the cover of the box beingremoved and the tray-holder being removed from one of the compartments.

A designates the body portion of the box, shown as of oblong form. Itmay be of any desired depth and has an open top.

B designates the cover for the box. The edges b of this cover, when thecover is in position upon the body, rest in a water lute or seal, formedin a trough or gutter b extending about the box near the top of thelatter. The trough b has a closed bottom, formed by a ange b2, extendinghorizontally from and about the body A. One of its side walls is formedby the body A and the other by side pieces b3, which extend upwardlyfrom the iiange b2 and somewhat above thc top of the body A.

The construction thus far described is not new.

C designates a trough or gutter which divides the upper part of the bodyA into two approximately square portions or compartments a a. The endsof this trough open into the trough b. lVater in the troughs b C willtherefore be in communication and at the same level in both. Gas entersat Athe ports c in the bottoms of the portions a a', and, in the exampleof my improvement shown, finds exit through a pipe c', extendingupwardly from the bottom of the gas-holder intermediate be tween theportions a a to a point above the water-level in the trough C. Theoutlet-pipe c', as it extends upwardly, gradually changes from acircular to an elongated form in crosssection, thereby economizing spacebetween the portions a a and affording ample space for receiving the gaswhich passes up through the trays.

D D designate tray-holders, in which trays or grids D2, which may be ofordinary construction, are supported upon internal ribs or flanges d,extending horizontally about the interior of the holders. Chemicalmaterial adapted to purity the gas is placed upon the trays or grids.The tray-holders D D are of approximately the same shape as the portionsa a and extend with a loose fit into them, and, when in position, nearlyto the bottom of the box A. They have open tops and bottoms. Near theirtops the said tray-holders are provided with horizontally extendingflanges d upon all sides. From the outer edges of the iianges (Zv,flanges d2 extend downwardly upon all sides. Then the holders are inposition the sides of the portions a a' ex tend into the space formedbetween the anges cl2 and the sidesof the holders, and the flanges d2 ofthe holders extend downwardly into the water lutes or seals formed inthe troughs or gutters D C. Between the iianges (Z2 and the side piecesb'1 is sufiicient space to receive the sides of the cover B when thelatter is placed in position. Gas entering through the ports c will passupwardly about and over the chemical material placed upon the trays inthe holders D D', and will, after being thus purified, pass outwardlythrough the pipe c.

XV hen the chemical material upon the trays or grids D2 becomesexhausted and needs revivifying or renewing, or when from any othercause it is desired to remove the chemical material from the portions aa', I lift out the tray-holders D D, and with them the trays D2 and thechemical material. This is conveniently effected by means of anysuitable tackle-engaging rings g with which the trayholders areprovided. This may be eected very quickly and avoids all shoveling ofthe chemical material from the trays or compartmcnts,as is now thecommon practice. The tray-holders having been lifted out, othertrayholders, which, in the intervals of charging, have been rciilledwith fresh material, may be as quickly lifted into position. Theoperation IOO of the purifier may in this Way be made practicallycontinuous, being interrupted only for a sufficient time to lift out oneset of trayholders and trays and insert a fresh set. The tray-holderswhich have been lifted out may be conveyed away in any suitable manneran d the material dumped from the trays Where desired. The trays maythen be refilled ready for a fresh charge.

Although I have shown and described two tray-holders, I may of courseuse any desired number.

It Will be seen that by my improvement very much time and labor aresaved, the great danger of asphyxiation which laborers expe-' take placearound the tray-holders it could easily be detected from the outside.

That I claim as my invention isl. In a gas-purifier, the combination,With the body portion of a box surrounded near its top With a Waterseal, of a cover adapted to extend into said Water seal, and a removable tray-holder supported in said box beneath the cover and providedWith a flange also extending into said water seal, substantially as setforth.

2. The conlbinatioinwvith abox and purifying compartment within the box,of a Water lute located between two purifying-compartments, and agas-outlet pipe extending from the bottom of the `gas-holder up withinthe Water lute and having its upper end transversely elongated,substantially as set forth.
